GMC Jimmy

typically, they are either before or after the cat converter. there may be multiple, even both before and after.

My 1999 has been doing this for years. I have learned to ignore it. No negative affect so far.

4.3 v6 is 165432 ----- 2.8 v6 is 123456

yes it can but also check the speed sensor if your vehicle is equiped with one.

you have an ehaust leak some close to the engine conpartment its probly where the headders/exhaust manifold meets the y pipe/cross pipe. depending on how bad of shape the exhaust system is. it may be rusted out or it might be the exhaust gaskets. if its not the exhaust then you have a fuel leak somewhere in the system. if its caurberated cheek to see if there is a bad odor from uder the hood then run through the fuel lines and look for leaking. im goinna go with the exaust though.

spark plug gap for 1994 gmc jimmy

If you are referring to the auto locks, there may be a blown fuse. Check the owner's manual for the specific location of the fuses for your model year.

find your miss placed owne's manual. locate the drainage valve-usaully a nut with washer. TURN LOOSE THE CAP ON THE RADIATOR WHEN THE ENGINE IS NOT HOT. turn loose the drainage valve and check if the washer is still good. after drain the whole thing and the content of the antifreeze reservoir. refill with water. run your engine for 5 minutes. drain again. tighten the drainage nut, change new washer if needed. add new antifreeze according to the label(add water to dilute). cap back, run engine for 10 minute, refill the reservoir to the max line indicated on the side of the plastic container. you are done. REMEMBER*****DO NOT DO THIS WHILE ENGINE IS HOT*****

Your air conditioning system is most likely has an insufficient amount of refrigerant.

The way your air condition system works is by compressing a gas refrigerant into a liquid. That liquid goes into the evaporator coil where it boils off and releases heat. Then the refrigerant passes through an expansion valve ( a tiny hole that only a small amount can pass through at a time) into the low pressure side of the system. Since there is a drop in pressure, the refrigerant begins to absorb heat.

Your compressor cycles because it has a low pressure switch on the low pressure side of the system. Your compressor turns on and begins to pump the refrigerant into the high pressure side. Since you have a low amount of refrigerant, the compressor can pump it into the high side much faster than it can pass back to the low side. The compressor pumps the level in the low side down past the cutoff point and the low pressure switch cuts it off. The gas leaks back into the low pressure side through the expansion valve like it should, bringing the pressure back above the cutoff level and the compressor kicks back on.

on the rear of the case there is a fluid fill line next to the fill bolt.

Remove fill bolt and stick your finger in.

Try replacing the windshield washer pump. There should be two pumps located on the washer reservoir. Simply unplug the electrical connector, pull the fluid tube off, lift them out. Put the new ones in the same place as the old ones. Place the fluid tube back and reconnect the electrical connector. The parts are pretty cheap about 15 bucks each from Autozone. Give it a shot. Overall it should take less than five minutes. Good luck.

Code P0753 is a shift solenoid code probably sticking so I would change the transmission fluid and filter then erase code.This should fix the problem.

Probley have a bad 4x4 Actuator in the front left side of the differential HOUSING. It is towards the center of the housing on the left when standing in the front of the truck.

Make sure that it is not the tire that is causing the noise- bearings last a ridiculously long time. And then- You need to go to a car parts store, and get a repair manual for your car. They cost about $16.00 Or, go to a Public Library.

Wheel bearings do go bad on these cars. They need to be pressed in and out. If you don't have the tool, you might be able to rent it from store. You also will need an acetylene torch b/c the suspension parts tend to rust together and form a very strong bond. First remove the hub nut with a 32 mm socket. Then remove the tires. After removing brake caliper and rotor, you need to get the hub assembly out by removing ball joint and swinging it to get clearance to pull out from cv joint. A made in china press might work, but you would be better off having something thicker and stronger metal to try and push it out, b/c it will be a tight fit.

The firing order for the 4.3L engine is 165432

Yes. One switch is for the left and right brake light assemblies; and, the other is for the 'third' brake light.

Remove steering wheel. Underneath is the turn signal switch. There is a ring around the steering shaft holding the steering wheel lock plate down. Push down on the lock plate and remove the ring and the lock plate. Next is the turn signal switch. 3 screws holding it down one on the right side above the key and 2 on the left. Probably have to move the turn signal switch left and right to get them. the arm is held on with one screw. Remove the hazard button, one screw in the end of it. There should be enough slack in the turn signal wires to get it over the steering shaft. On the top side at the bottom of the ignition switch there should be a screw. Remove screw and the ignition switch will just pull out. Reverse to install.

from what i am hearing a lot of is that it is either the accuator on the driver side to the right of the gas pedal or the baffle door itself is broken(costing a sh*t ton of money to fix have to remove the dash). there is a while plastic piece that has a tendency to break on the end of the accuator that goes into the box. some ppl use a bent coat hanger to push the baffle through the driver side floor vent to get it to move so you get floor heat, then disconnect the red and blue vaccume hoses off the accuator to prevent the baffle from moving. use a nail or tape to stop the vaccume leak . you should still have all you functions for the rest of your heat controls. just the floor and defroster wont switch back and forth. they will both work at the same time. this is the case for each the blazer, jimmy, sonoma, s10, zr2 1998 and up. if you still have your heat working on the floor id suggest that if you own one of these vehicals that you don't turn your defrosters onto full fefrost mode. just floor defrost. what happens is the accuator by the gas pedal when placed in full defrost mode places to much force on the white plastic piece and snaps it, or the piece that's just inside the box. if you put into floor / defrost mode the accuator works as intended.. its mostly a design flaw from gmc that was never made public. it was a volintary recall item

in the intake manifold

was the engine removed before the overhaul or was the overhaul carried out in the vehicle? was the engine removed before the overhaul or was the overhaul carried out in the vehicle?

How can I stop the motor from spinning

Depending on engine wear, some engines prove difficult to stop from spinning! Jamming things in the pulleys only subject you to unwanted damage. Impact seems to be the most successful way to loosen a clutch fan. using a large adjustable wrench or open end wrench. Do not remove serpentine. Smack tool with large hammer while assistant helps you stabilize pulleys from moving. This might take several attempts. Good Luck!

follow the large hose leaving the radiator it will end at the thermostat top center front of the engine 2 bolts off it goes

The 1995 GMC Jimmy base model 4-door SUV has a curb weight of 3,666 pounds, and a gross weight of 4,785 pounds. Its maximum towing capacity when new was 5,500 pounds.

look at the transfer case,theres a fill hole and a drain hole both with bolts to take out. You can also search on youtube to see a vid.

under the driver door is the filter. keep the attachmen nut tight, use two open-end wrenches to loosen the gas line.

do not remove them after you loosen them or gas will drench your face.

loosen the nut, make sure that when you replace it the intake is pointed the right way.
